Hosted by: Fraser Cain and Dr. Pamela L. Gay Normally we try to end the season on a high note. But there’s unfolding news that we just HAVE to cover before we leave you for the summer. NASA’s new budget is here, and it’s 25% smaller. We’ll cover what the changes are and try to understand the implications. It's a bad decade to be a researcher. We're going to look at why, and what US cuts will mean for the world.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

The Vera Rubin Observatory By Fraser Cain & Dr. Pamela Gay Streamed live June 25, 2025. The time has come. The mighty Vera Rubin Observatory has finally come on line and delivered its “first light” images. And by Pamela’s rules that means we get to talk about it! So let’s do that! After decades of waiting, we have images from Vera Rubin Observatory!   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

It’s almost time for our annual summer hiatus, but before we go, we wanted to direct you towards all the fun and space stuff we’ll be enjoying this summer. We’ve got meteor showers, planets, rocket launches, TV shows, movies! Here’s what’s good. In a couple of weeks, we'll go on hiatus, but we want to make sure you are ready for stuff we can anticipate happening.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

Humanity has turned its focus back to the Moon, sending a fleet of spacecraft to the lunar surface. Some are run by the government, but there’s a whole new group of commercial landers bearing instruments to the lunar surface. Is this the future of lunar exploration? Space used to be a place occupied by government-funded and military missions, but today, we're seeing the rise... and fall (somersault, crash, and explosion) of missions with commercial design and funding. Let's talk about how this is good, bad, and maybe just too soon.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

Some of our favorite robots are rovers currently roving around the surface of the Moon & Mars. But there’s some pretty tricky terrain out there and engineers are scheming up clever ways to explore other worlds inspired by life that crawls, slithers, hops and flies. As we explore more surfaces and more complex surfaces throughout the solar system, mission teams are designing robot explorers that don't sit still and also don't rove. In this episode, we're going to take a look at the new technologies that are allowing technology to get around.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.  Join at the Galaxy Group level or higher to be listed in our YouTube videos.  Thanks to: BogieNet, Stephen Vei, Jeanette Wink, Siggi Kemmler, Andrew Poelstra, Brian Cagle, David Truog, Ed, David, Gerhard Schwarzer, Sergio Sancevero, Sergey Manouilov, Burry Gowen, David Rossetter, Michael Purcell, Jason Kwong Astronomy Cast Ep. 757: CubeSats Mon, 26 May 2025 20:00:00 +0000 33:13 false 18 757 full Astronomy Cast Ep. 757: CubeSats By Fraser Cain & Dr. Pamela Gay Streamed live on May 19, 2025. Computers are getting smaller, faster and more capable, which has enabled an entirely mew class of satellites: CubeSats. A mission small enough that you can hold it in your hands, and yet powerful enough to even travel to other planets and send messages home.    Every year, our electronics seem to get smaller and more powerful, with today's smart watches being more fully featured than the computers Pamela and Fraser had as little kids. These tiny processors, sensors, and transmitters are allowing tiny satellites with powerful functionality, and today we take a look at how this is changing space exploration.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

NASA’s newly launched SphereX mission is up & operational and has completed its initial checkout and “first light”. Everything looks good! And now it’s starting its science operations. And that’s good enough for Pamela! And THAT means we can talk about it. So let’s do that! There's a new space telescope in town (or at least in LEO). Let's check out what it's looking at and looking to do.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

Hosted by: Fraser Cain and Dr. Pamela L. Gay. There are stellar-mass and supermassive black holes. But very little evidence of anything in between. Where are all the intermediate-mass black holes that should be the building blocks of the biggest ones? Actually, the science has been accelerating rapidly and we now know of hundreds of them. The question marks in our understanding are slowly getting replaced with data. Let's review what we now know about intermediate mass black holes and their origins.    SUPPORTED BY YOU!

You’ve heard the news! Astronomers are reporting the discovery of biosignatures at K2-18b. Is this proof of life or should we all be more skeptical?

I’m sure you’ve heard that all eyes are on the Moon’s southern pole. This is where various  NASA and Chinese missions are targeting. What makes this region so special and what are the special challenges that explorers will face.

Hosted by: Fraser Cain and Dr. Pamela L. Gay There is an ongoing debate on where NASA should go next with humans: to the Moon or Mars. (Or maybe an asteroid or one of Mars’ moons). We are on the verge of sending humans back to the Moon. At the same time others would prefer we focus our exploration on Mars. It’s a tough choice because there are costs and benefits to both. Let’s try to give this conversation some nuance. Let's discuss the reasons for each of these worlds.   SUPPORTED BY YOU! This Episode is made possible thanks to our Patrons on Patreon.

Hosted by: Fraser Cain and Dr. Pamela L. Gay. Even empty space isn’t empty. It’s filled with the quantum fluctuations of spacetime itself. Which can be measured with famous experiments like the Casimir Effect. There is a surprising amount of energy in space itself, which has led to some interesting theories about how the future of the Universe might evolve.

Hosted by: Fraser Cain and Dr. Pamela L. Gay When enormous stars detonate as supernovae they release a burst of neutrinos that can be the first sign of a coming explosion. Now, astronomers have built a network to watch for that flash of neutrinos, and help direct their telescopes for when the sky show begins. Supernovae explosions occur in stages, with neutrinos being emitted hours before photons. If we can accurately detect those neutrinos, we might just be able to get on target before the light show even starts.... Maybe.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon. Join at the Galaxy Group level or higher to be listed in our YouTube videos.

The Hubble Tension is a vexing problem, with astronomers measuring the expansion of the Universe at different points in its history and getting different results. Errors have mostly been ruled out, which leaves the potential for new physics. Has the strength of dark energy been changing over time? We thought Dark Energy was constant with time, but new results from DESI say maybe not, and honestly, if it wasn't constant the Hubble Tension would be a whole lot easier to solve.   SUPPORTED BY YOU!

Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to.

Join us for the first episode of Season 18 as we review all the crazy space science that happened during our Summer Hiatus.  Astronomy Cast Ep. 173: Herschel Space Observatory - REMASTER Mon, 26 Aug 2024 20:00:00 +0000 25:15 false 17 173 full Astronomy Cast Ep. 173: Herschel Space Observatory - REMASTER By Fraser Cain & Dr. Pamela Gay From January 18, 2009. Last week we talked about Herschel the people – William Herschel, his sister Caroline, and his son John. This week we look at the Herschel Space Observatory, a mission launched in 2009 to reveal the coldest and dustiest regions in the Universe. Astronomy Cast Ep. 172: William Herschel - REMASTER Mon, 19 Aug 2024 20:00:00 +0000 25:33 false 17 172 full Astronomy Cast Ep. 172: William Herschel - REMASTER By Fraser Cain & Dr. Pamela Gay From January 11, 2010. Ancient astronomers knew of 5 planets, Mercury, Venus, Mars, Jupiter and Saturn – 6 if you count Earth. And then in 1781, William Herschel discovered an entirely new planet, Uranus, boosting the number of planets to 7. Let’s learn about Herschel, his equipment, his discoveries, and his sister Caroline – an accomplished astronomer all on her own!

We’ll talk about it today.   This video was made possible by the following Patreon members: Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Ep. 694: Mission Roll Call Part 3: Sun, Mercury, and Venus Mon, 23 Oct 2023 20:00:00 +0000 33:54 false 17 694 full Astronomy Cast Ep. 694: Mission Roll Call Part 3: Sun, Mercury, and Venus by Fraser Cain & Dr. Pamela Gay Streamed live on Oct 16, 2023. Our journey through space missions continues. Now we move away from the Earth to the rest of the solar system. What’s out there orbiting, roving and flying on other worlds and in interplanetary space. Today we look inward and we’ll talk about the missions studying the Sun, Mercury and Venus.   Thank you to all of our patrons who allow us to do this!

Last week, we brought you up to speed on the spacecraft which are helping to study Earth from above. Many of our missions are in Earth orbit but looking outward to study the Universe. Today, we’ll talk about the missions close to home, helping us understand our place in the cosmos.   This video was made possible by the following Patreon members: Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 692: Mission Roll Call Part 1: Earth Orbit Mon, 09 Oct 2023 20:00:00 +0000 29:36 false 17 692 full Astronomy Cast Ep. 692: Mission Roll Call Part 1: Earth Orbit by Fraser Cain & Dr. Pamela Gay It’s time for another series! This time we’re gonna look at the missions that’re currently in place across the solar system. Today we’ll start with the key missions here on Earth, studying the planet from above and looking out into the Universe.  Astronomy Cast Ep. 691: Jupiter’s Changing Red Spot Mon, 02 Oct 2023 20:00:00 +0000 29:14 false 17 691 full Astronomy Cast Ep. 691: Jupiter’s Changing Red Spot by Fraser Cain & Dr. Pamela Gay Streamed live on Sep 25, 2023. Jupiter’s Great Red Spot is one of its most iconic features. First seen hundreds of years ago. Although it’s certainly long lasting, it’s been changing in size over the last few decades. Shrinking, changing in color. Is it fading away? And what can the changes tell us about storms on giant planets?

We’ve looked at Earth’s changing climate, now let’s see what it’s like for another world: Mars. Much looks familiar, but some of it is totally alien, from ice caps of frozen carbon dioxide to planetary dust storms that can obscure the entire world from view.   This video was made possible by the following Patreon members: Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 689 - Our Warming World: 20 Years of Climate Science Mon, 18 Sep 2023 20:00:00 +0000 37:55 false 17 689 full Astronomy Cast Ep. 689 - Our Warming World: 20 Years of Climate Science by Fraser Cain & Dr. Pamela Gay Streamed live on Sep 11, 2023. It’s official! June and July were the warmest we’ve seen since records began over a century ago. Fires are rampant across Canada, and we’re seeing record droughts around the world. Today we’re going to look at 20 years of climate science, how well does reality match up with the predictions.   This video was made possible by the following Patreon members: Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast - Hiatus Message Mon, 10 Jul 2023 20:00:00 +0000 04:24 false 16 full Astronomy Cast - Hiatus Message by Fraser Cain & Dr. Pamela Gay Once again, we’ve reached the end of a season here on Astronomy Cast, and it’s time for the summer hiatus.

Looking Ahead to Season 17 by Fraser Cain & Dr. Pamela Gay Streamed live on Jun 26, 2023. Once again, we’ve reached the end of a season here on Astronomy Cast, and it’s time for the summer hiatus. But the Universe never takes a break. What can we expect to happen over the summer while we’re catching up on our reading, building our gardens and planning for Season 17?   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 687: Prepping for the Moon Tue, 27 Jun 2023 02:50:51 +0000 34:02 false 16 687 full Astronomy Cast Ep. 687: Prepping for the Moon by Fraser Cain & Dr. Pamela Gay We’re going back to the Moon. In the next few years humans will set foot on the Moon again, ideally this time to stay. But this will be different than the Apollo era, going to the scientifically fascinating, and difficult southern pole of the Moon. What needs to be done to prepare the way back to the Moon?   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 686: Ice In The Shadows Mon, 19 Jun 2023 20:00:00 +0000 27:20 false 16 686 full Astronomy Cast Ep. 686: Ice In The Shadows by Fraser Cain & Dr. Pamela Ga Streamed live on Jun 12, 2023. The permanently shadowed craters on the Moon are the focus of so much research. That’s because they seem to contain vast reserves of water ice. Water we could use for oxygen, propellant and so much more, but also, to help us understand where the Earth’s water came from.   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Jeanette Wink Andrew Poelstra Brian Cagle David Truog BogieNet Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela   Astronomy Cast Ep. 685: Manufacturing In Space Mon, 12 Jun 2023 20:00:00 +0000 29:32 false 16 685 full Astronomy Cast Ep. 685: Manufacturing In Space by Fraser Cain & Dr. Pamela Gay Streamed live on Jun 5, 2023. Launching satellites from Earth is counter-productive. You’ve got to make a satellite that can handle Earth gravity, then the brutal flight to space, then deployment in orbit.

One of JWST’s top jobs is to peer deeper into the Universe than ever before, watching as the first galaxies came together. Surprisingly, astronomers found galaxies that seemed much more mature than expected, much earlier than it was believed possible. What’s going on and what does it mean for cosmology?   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Jeanette Wink Gerhard Schwarzer David BogieNet THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 683: Cosmic Dawn Mon, 29 May 2023 20:00:00 +0000 26:54 false 16 683 full Astronomy Cast Ep. 683: Cosmic Dawn by Fraser Cain & Dr. Pamela Gay Streamed live on May 22, 2023. After the cosmic microwave background radiation was released, the Universe returned to darkness, cloaked in this clouds of primordial hydrogen and helium. Gravity pulled these vast clouds into the first stars, and then the first galaxies. This is Cosmic Dawn, and JWST will help us probe this mysterious time in the Universe.   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Jeanette Wink Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 682: Ultra-Diffuse Galaxies & Dark Matter Mon, 22 May 2023 20:00:00 +0000 28:33 false 16 682 full Astronomy Cast Ep. 682: Ultra-Diffuse Galaxies & Dark Matter by Fraser Cain & Dr. Pamela Ga Streamed live on May 15, 2023. Astronomers first noticed the strange behaviors of rotating galaxies almost 100 years ago, suggesting there’s an invisible dark matter hold them together with gravity. Or maybe we just don’t understand how gravity works at the largest scales. Observations are much better now, and astronomers have found examples of galaxies that are almost entirely made of dark matter. Does this tell us anything?   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Jeanette Wink Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela   Astronomy Cast Ep. 681: Kilonovae Mon, 15 May 2023 20:00:00 +0000 29:50 false 16 681 full Astronomy Cast Ep. 681: Kilonovae by Fraser Cain & Dr. Pamela Gay Streamed live on May 7, 2023. In 2017, astronomers detected the gravitational waves and electromagnetic radiation from colliding neutron stars. This had been long theorized as one of the causes of a certain type of gamma-ray burst. By studying the event and its afterglow, astronomers have learned a tremendous amount about the formation of the heaviest elements in the Universe.   This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Jeanette Wink Gerhard Schwarzer David THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 680: Rogue Black Holes Mon, 08 May 2023 20:00:00 +0000 27:58 false 16 680 full Astronomy Cast Ep. 680: Rogue Black Holes by Fraser Cain & Dr. Pamela Gay Streamed live on May 1, 2023. Last week we talked about rogue stars. This week we’re going to take things up a notch and talk about an even more extreme event. Rogue black holes. Astronomers recently discovered a supermassive black hole on an escape trajectory, leaving newly forming stars in its wake. It’s wonderful, terrible, nightmare fuel.

Most stars in the Milky Way are trapped in here with us, doomed to orbit around and around and around. But a few have found a way out, an escape into the freedom of intergalactic space. How do stars reach escape velocity, never to return?   This video was made possible by the following Patreon members: David Burry Gowen Stephen Veit Jordan Young Jeannette Wink Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 678: World Building: Planet Formation, Growth & Ejection Mon, 24 Apr 2023 20:00:00 +0000 29:38 false 16 678 full Astronomy Cast Ep. 678: World Building: Planet Formation, Growth & Ejection by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 17, 2023.

Whenever astronomers discover something surprising, the answer often turns out to be dust. Dust obscuring our view, dust changing the polarity, dust warming things up, dust cooling things down. It’s always dust. Until it isn’t.   This video was made possible by the following Patreon members: David Burry Gowen Stephen Veit Jordan Young Jeannette Wink Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 676: Other Things With Rings Mon, 10 Apr 2023 20:00:00 +0000 30:54 false 16 676 full Astronomy Cast Ep. 676: Other Things With Rings by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 3, 2023. We’ve spent a lot of time gushing about Saturn’s rings, but there are other places with ring systems. And not just Jupiter and the ice giants, but asteroids, dwarf planets, centaurs and even exoplanets. Today let’s gush about them!   This video was made possible by the following Patreon members: David Burry Gowen Stephen Veit Jordan Young Jeannette Wink Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 675: Exotic Forms of Ice Mon, 03 Apr 2023 20:00:00 +0000 30:05 false 16 675 full Astronomy Cast Ep. 675: Exotic Forms of Ice by Fraser Cain & Dr. Pamela Gay Ice is ice, right? You know, what you get when water freezes. Well, maybe here on Earth. But across the Universe, water can be squeezed together at different temperatures and pressures, leading to very different structures. Today we’ll talk about the different forms that ice can take.   This video was made possible by the following Patreon members: David Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 674: Asteroid Early Warning Systems Mon, 27 Mar 2023 20:00:00 +0000 30:36 false 16 674 full Astronomy Cast Ep. 674: Asteroid Early Warning Systems by Fraser Cain & Dr. Pamela Gay The asteroid apocalypse is one of those existential crises that keep astronomers up at night. But the DART mission showed us that we can push an asteroid off its trajectory if we have enough warning. Today we’ll talk about how humanity is building early warning systems to give us time to respond to a dangerous asteroid.   This video was made possible by the following Patreon members: David Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 673: How to See Satellites (or Avoid Seeing Them) Mon, 20 Mar 2023 20:00:00 +0000 34:37 false 16 673 full Astronomy Cast Ep. 673: How to See Satellites (or Avoid Seeing Them) by Fraser Cain & Dr. Pamela Gay Streamed live on Mar 13, 2023. If you’re in dark skies and look up, you’re certain to see a satellite. Lots of them. But how can you know which one you’re seeing, and how can you improve your chances of a sighting?

The Universe was inaccessible for most of human history, but the first tentative steps to space in the 20th Century made humanity realize that science fiction was becoming science reality. New rules would have to be written to govern how we used this limitless expanse. Today we’ll talk about the Outer Space Treaty of 1967.   This video was made possible by the following Patreon members: David Burry Gowen Jeanette Wink Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela   Astronomy Cast Ep. 669: Challenges to Dark Energy Mon, 13 Feb 2023 21:00:00 +0000 29:17 false 16 669 full Astronomy Cast Ep. 669: Challenges to Dark Energy by Fraser Cain & Dr. Pamela Gay Streamed live on Feb 6, 2023. It’s been over 20 years since astronomers first discovered that the expansion of the Universe is accelerating thanks to dark energy. And in these decades, astronomers still don’t have much evidence for what could be causing the increased expansion rate. Maybe there’s something else going on to explain it.   This video was made possible by the following Patreon members: David Burry Gowen Jeanette Wink Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela Astronomy Cast Ep. 668: The Crisis In Cosmology Mon, 06 Feb 2023 21:00:00 +0000 30:51 false 16 668 full Astronomy Cast Ep. 668: The Crisis In Cosmology by Fraser Cain & Dr. Pamela Gay Streamed live on Jan 30, 2023. Astronomers have made extremely accurate measurements of the expansion rate of the Universe and come up with different results. And the error bars for the observations don’t overlap, so there’s something strange going on.
